1.Features
High concurrent number of users
One head facility can carry 63 concurrent users,
it also can be upgraded to 127 and according to request, this fully satisfies the demand about the concurrent number of users,High bandwidth
The physical layer transmission bandwidth is up to 200Mbps.it can provide effective 100Mbps bandwidth for all users connected the head facility .That fully satisfies the family users' demand on all broadband business application.
High anti-jamming
PLT800R system adopts OFDM(Forward Error Correction) and chanel auto-negotiation technic.Every carries wave frequency can choose close up or turn on.That can avoid interference coming from the brodadcasting station and radio.
Small rebuilding work
Regarding the current HFC network , besides it is needed to bridge with duples fiter where there requires single unidirection amplifier , and no need make transformation on other line .As long as install according PLT800R facility , it will realize data broadband access and then achieve the directional rebuilding .
